Symbionts such as Rickettsia in whiteflies and Buchnera in aphids are transmitted ________ to ensure the safe transfer of the symbiont to the next host generation.

Question

Quizplus · Accepted Answer

Symbionts like Rickettsia and Buchnera are transmitted vertically, meaning from an infected parent to its offspring. This ensures the safe transfer of the symbiont to the next generation of hosts. Horizontal transmission, on the other hand, occurs between unrelated individuals and can be risky because the symbiont may not be compatible with the new host or may be lost during the transmission process. Vertical transmission is typically achieved through some form of direct contact or passage from the parent to the offspring, such as through the egg or other reproductive tissues.
